The existence of photovoltaic connectors is mainly to protect components. When components in the array become hotspots due to obstacles such as dark clouds, branches, bird droppings, etc., the diodes in the components utilize their unidirectional conductivity to bypass problematic batteries and battery strings, thereby protecting the entire component and even the entire array, ensuring that it can maintain the necessary working state and reduce unnecessary losses.
Simply put, the role of photovoltaic connectors in solar cell modules can be summarized into two points:
Connection and transmission functions;
Protect components; It is a comprehensive design that integrates electrical design, mechanical design, and materials science.
Photovoltaic connectors have the characteristics of fast and reliable connection, waterproof and dustproof, and easy to use. The shell has strong anti-aging and UV resistance. The cable adopts a compression connection, and the male and female heads are fixed by a stable self-locking mechanism, which can be freely opened and closed. It is an indispensable and important component of the solar power generation lighting system; The scientific structure and selected materials of the product ensure good mechanical and electrical performance.
